nephrin CRISPR Activation Plasmid (m) | sc-424905-ACT | 20 µg | $397.00 |
Mouse Nphs1 encodes nephrin, a transmembrane immunoglobulin superfamily protein that forms the core of the podocyte slit diaphragm and is essential for glomerular filtration barrier integrity. Nephrin participates in multiprotein complexes with podocin and CD2AP and connects to actin cytoskeletal remodeling through signaling pathways including PI3K/AKT and Src-family kinases, supporting podocyte survival and architecture. Perturbation of nephrin expression or localization disrupts slit diaphragm structure, leading to altered permeability and proteinuria-associated phenotypes widely studied in kidney disease models. As a podocyte-enriched marker, Nphs1 regulation is frequently interrogated in studies of glomerular development, injury responses, and filtration barrier maintenance.
nephrin CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Nphs1 expression without altering the underlying DNA sequence.
nephrin CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Nphs1 locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the Nphs1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous nephrin expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Nphs1 locus and enabling the study of nephrin-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of nephrin pathway restoration in tumor cells with silenced or reduced Nphs1 expression.
